The first week passed with little trouble. The second week however, well, let's just say that the Slytherins were still upset.

Sirius grunted as he was shoved forcefully to the side. "Hey, watch it!" He shouted. He brushed off his robes and continued walking to Potions with Remus.

They entered the dungeon and took their usual spots in the back. "Today we will be continuing our Alihotsy Draught. Begin." Slughorn said and sat down.

Remus began preparing the powdered crystal while Sirius stirred the potion they had started yesterday. 4 times clockwise, 18 times counterclockwise. read the book.

After he stirred the cauldron, Remus tipped the sparkly power into it. The potion turned dark and started puffing out blue fumes. "I think we did it right." Sirius said as he compared the potion to the book's description.

Remus raised his hand to get Slughorn's attention, who stood up and walked back to them. "Yes yes. Very good. You may take the rest of the period off."

Remus and Sirius grinned excitedly at each other as they left the classroom. As soon as the door shut behind them, they took off running through the halls back to Gryffindor Tower.

They burst into their dorm room and, throwing their stuff down on the beds, began to plan their first prank.

"Okay, Peter overheard a few 6th years saying that the Halloween one starts at 10pm." Remus said, shuffling a few papers around.

"We'll need to find a way to the old tower without getting caught out of bed..." Sirius muttered as he flopped across Remus's bed.

"Maybe follow the 5-7th years when they leave?" Remus suggested as he made notes on his plans.

"But we need to do it without being seen. How do we do that?" Sirius asked as he rolled over and hung upside down off the bed.

Remus looked up at him. "One, you'll pass out if you stay like that for too long. Two, we'll get Peter and James help with figuring that out."

Sirius frowned in concentration. "Okay...so are we going to gate-crash or are we going to gate-crash?"

Remus smirked. "We're going for elaborate and dramatic pranks here. I don't do it any other way."

"Hmm." Sirius hummed and sat up slowly. He sat back against Remus's pillows and pulled out his journal. "Hey Remus, got an extra quill I could borrow?" He asked and Remus handed one up to him.

Sirius began to make small notations of their prank but dtoon became bored and started drawing instead. He glanced over at Remus, who was staring intensely at something on the page, and began to draw him.

Seconds turned to minutes and minutes turned to half an hour and then James and Peter flung open the door, causing Sirius to slam his journal shut and hide it. Remus didn't even glance up from his many pieces of parchment.

"Sirius still-not-sure-on-your-middle-name-but-probably-Orion Black!" James yelled. Sirius raised an eyebrow at him. "You need to see this Muggle thingy that Peter has!"

Peter, who was laughing his ass off, held out a small can. Remus saw it and began laughing too. Sirius huffed and walked over.

"Okay. Its a can. What does it do?" He asked. "S-shake it, then p-pull this t-tab up to o-open it." Peter said.

Sirius heard Remus fall over laughing behind him. He grabbed the can, shaking it viciously then popped the top.

A spray of fizzing white foam erupted from it, dripping down onto the carpet. "Peter!" Sirius screeched, and the boy sank to his knees from laughing too hard.

"What is all the commotion up here?" A stern voice asked and the four looked over to see McGonagall standing in the doorway.

"Oh umm you see professor" Remus began, still giggling, "Peter was just showing Sirius the wonderous inventions of the Muggle world. Such as soda."

"Hmmph." McGonagall said. "Clean up this mess." She turned away and left the Marauders alone.

James sighed in relief as Sirius glared at the still laughing Peter and the giggling Remus. "You did that on purpose." He accused them, and Peter nodded.

"Well, you have pranked me with your Muggle soda, now I shall prank you." He smirked devilishly and stalked out of the room, still holding the dripping soda can.

It was that night at dinner that Sirius put his prank into action. He'd gone to the Potion's room and nicked some of their completed Alihotsy Draught. If they'd done it correctly, it should cause hysteria.

"Hey Remus, Peter. I think that Snivillous Snape is trying to get your attention." Sirius said and the two boys turned around. Quickly, he emptied the vial into their drinks and sat back down.

"I don't see him." Remus said, turning back around. Sirius shrugged. "I may have misinterpreted what he was doing."

Remus's nose twitched, which they had learned was another way of him shrugging, and he took a drink out of his glass.

Almost immediately, he started to smile and giggle. Peter, who had done the same, was also giggling. The giggles drew out, becoming laughs.

"What's. H-happening?" Peter choked out. Remus glared at Sirius. "I've got hahaha an idea hahaha."

Sirius smirked at the two, who were laughing more and more now. A couple of people glanced over at the group of four.

Two hours later, Sirius sat in McGonagall's office. "Now Sirius, I understand why you would want to prank them back. But please do not do it in a way that results in hysterical laughter during dinner."

Sirius nodded an she waved a hand. "Off you go."

"Thank you ma'am." He said and left the room.

"So?" James asked him as the door closed. Sirius grinned. "Got off with a warning."

"Awesome!" James said. "Now we can still pull off Halloween without any problems like detention!"

Sirius nodded and the two of them walked down the hallway back to Gryffindor Tower, where Remus and Peter awaited them.
